Hello, Very shortly I will be getting this HD for my 13" mid 2009 MBP. First though, I have a couple of questions about it: 1. I'm quite confident it will fit, as it is a 2.5 inch, but I want to make sure the height and everything is ok. Here are the physical specs: Height 9.7mm (0.378 in) Width 70.10mm (2.76 in) Length 100.55mm (3.959 in) Weight (typical) 110g (.238 lb) 2. As it is a 7200 RPM hard drive, will it cause my battery life to suffer all the time, or only when I'm reading/writing things to the hard disk where I need the hard drive to be spinning at 7200 RPM? Here's the link to the site I'm buying it off: http://www.ascent.co.nz/productspecification.aspx?ItemID=388946 BTW: Please don't suggest places where I could get it cheaper, as those places will probably be in the USA, where I don't live This is a trusted NZ website with free shipping anywhere in the country, so it suits me just fine. Thank you very much!
